Actually, when I went to USAF water survival school, the best
devices were the signal mirror and strobe light.
Sweep the horizon with the mirror. Use your strobe at night.
The radio is in a plane at 35k, or a ship on the horizon...
For most aircrew, the first thing that sinks to the bottom, is the
survival radio, after the first 100 ft wave crashes over your raft.
Water, food, puke, etc, it's all lost in the first 10 minutes...

Pray tell - how does one generate CW using only a spark gap transmitter?
The last time I looked, they generated damped waves - certainly NOT CW.
Throw an alternator in there, and you may have a point.
Wasn't this covered on the Novice exam?

One can use lots of sparks ...
Simple spring and magnet device will do the trick to make the sparks,
couple to any old tuned circuit. e.g. doorbell plus wax paper roll inductor,
plus tin foil and wax paper capacitor. Works. Done it.
The problem is the wire. When lost in the mountains, you first have to
locate some appropriate ore, smelt it, draw the wire. Big project. Good
to have iron or nickel, since you might want to make that magnet ...
.. after you made some tools to handle the wire drawing ...
Probably simpler to locate a garage sale. You can find everything
you need at most any garage sale.
